AMD Radeon HD 6850 Overclocking Roundup: Asus, XFX, & MSI
by Ryan Smith on November 8, 2010 12:40 AM ESTMeet The Asus EAH6850
Our second card today is Asus’s first Radeon HD 6850, the EAH6850.The EAH6850 is the latest member in Asus’s Voltage Tweak subseries of cards, offering official voltage modification capabilities for overclocking through Asus’s SmartDoctor utility. It’s also the first overclocked card in today’s roundup, featuring a stock speed of 790MHz core and 1000MHz memory, a mere 15MHz over the 6850’s standard clocks. As a result the overclock is a token overclock at best - it’ll edge out stock-clocked cards in testing, but the difference is nothing to write home about.
In terms of design Asus has more or less completely thrown out the 6850 reference design for their own design. Starting with the PCB, Asus has gone with a custom PCB that runs a half-inch longer than the reference PCB, giving the EAH6850 a final length of 9.5”. With this extension Asus has moved the 6pin PCIe power socket to the top of the card, removing the need for additional clearance behind the card and in the process making the power socket much more accessible. Notably there’s a spot for a second power socket, and given the longer length of the card we wouldn’t be surprised if Asus ultimately released a 6870 using this PCB.
Meanwhile the component selection on the card is the usual mix of solid state capacitors and chokes. We haven’t been able to identify the VRM components in use, but we believe Asus is using a different VRM arrangement than on the reference 6850. The card also features a metal spine running down most the length of the card, providing the extra rigidity that a longer card requires and preventing it from significantly flexing.
Attached to the top of the card is the now customary Asus DirectCU cooler, Asus’s highly effective cooler which we have seen on a number of Asus cards in the past. This open-ended cooler uses a pair of aluminum heatpipes attached to a copper baseplate to transfer heat to the card’s aluminum heatsink, which runs roughly 2/3rds the length of the card. Embedded in the middle of the heatsink is the 70mm “dustproof” fan, and a partial shroud keeps airflow directed out the front and the rear of the card. Meanwhile the MOSFETs serving as part of the VRM circuitry have their own heatsink attached through springloaded clips, with airflow coming off of the fan keeping this second heatsink cool.
As is the case with the other partner cards in today’s roundup, Asus has ditched AMD’s 6800 series Eyefinity port configuration in favor of the 5800 series Eyefinity port configuration. This means the card has two DVI ports and the HDMI port along with one full-size DisplayPort, allowing the card to drive up to 5 monitors through a DP hub.
Because this is a Voltage Tweak card, Asus’s software plays an important role here by providing control for the card’s voltage modification capabilities. SmartDoctor has not changed since the last time we’ve seen it, providing a functionally competent but ultimately second-rate overclocking experience, as SmartDoctor lacks meaningful monitoring capabilities. Truth be told, the latest betas of MSI’s Afterburner software are able to program the EAH6850’s VRM controller, meaning there’s no practical reason to use SmartDoctor as the superior Afterburner is available.
As for pack-in items, Asus includes their usual collection for an AMD card: a quick-start manual, driver/utility CD, molex-to-PCIe power adaptor, short CrossFire bridge, a pleather CD binder, and a DVI-to-VGA dongle. Which on that note we had a chance to talk to Asus’s video card product manager last week and asked about the VGA dongle – it turns out that while VGA is largely dead & buried in North America, it’s alive and well in the Asia-Pacific region. Asus is simply packing their cards the same way in all regions, which means they all come with the VGA dongle.
Finally, the EAH6850 comes with Asus’s standard 3 year video card warranty. EAH6850 can be found for around $185, putting it at a $5 premium over AMD’s MSRP.

You guys honestly didn't include the 460 ftw in the charts after the whole mess with the launch article, or at least mention it in passing in your conclusion? Sure I can go back and compare the results with the past articles but that not the point. Here's your chance to compare overclocked cards to overclocked cards and you don't even mention it.This article really must be a joke after all it ends with an overclocked "kicking" a reference 460 to the "curb"

If it's not mentioned, then it is not mentioned. You said it yourself that you can just grab the numbers from the launch article. So why complain about it? If you believe that this is an omission or something missed, why can't you just point it out instead of making a fuss about it?whatthehey - Tuesday, November 9, 2010 - link
(I'm posting here because otherwise you get lost in the fanboy "debate" below.... My response isn't really to either of the above two readers.)You know, I didn't get into the initial 6850 + 460 FTW brouhaha because I figured any sensible being wouldn't have a problem with it. I also didn't bother wading through any of the comments on the "what do you want" follow up. I thought the amount of noise a select few made was stupid then, and it's even dumber now!
AnandTech, you first need to wade through the users posting comments and do some research on past "input". Half of the users complaining and calling your credibility into question have no credibility to begin with! I swear there were a ton of new users that we have never heard from before. Seriously, do a Google on the most vocal user names and this site. Here are the nay-sayers posting on this article's comments; most of the others (i.e. 7Enigma in particular) are mostly interested in the bottom line rather than fanboy rage. So, here's a Google of site:www.anandtech.com {username}.
AnandThenMan: almost never a nice thing to say, and definitely anti-Nvidia. Vote: AMD fanboy
vedye: Never posted before GTX 460 and anti-Nvidia. Vote: AMD fanboy
spigzone: Off and on poster over time, but EXTREMELY vocal on the 460 FTW issues. Definitely a squeaky wheel, but only represents ONE person.
Ramon Zarat: Past posting history indicate strong AMD/ATI preference. Vote: AMD fanboy
If you were to wade through the mass of posts on the two 6800 articles and eliminate flame wars, trolling, etc. you probably only get about 10% of the posts, and they're still a minority.
I'd say the vase majority of us simply want more data. Had you overclocked a 6850 in the initial review, there would have been nothing to stand on. Maybe a simple statement of, "Time constraints (and lack of a retail card) led us to running stock settings; we'll be back next week with more data on 6850 overclocking." What's really stupid is that the conclusion wasn't even in favor of the GTX 460. All it said was, "yes, an overclocked 460 can do quite well, but it draws more power and costs more so it's not really desirable."
This is making mountains out of mole hills and then some. Move along, nothing to see here people. AMD and NVIDIA both compete fairly well. AMD has a better midrange part right now, but NVIDIA has faster parts if you're willing to pay the price and power. Two years ago it was all NVIDIA, and back in the 9800 days it was all ATI.

I still love the fanboys debating for some more performance there and a little less there. Trading blows for some more peanuts on a side and you trow in a 5-10$ difference then light they'll bring wood and burn someone on a stake.And when there's not enough difference to speak of then they throw in driver issues and such not so credible arguments. Or how they toasted every card they bought from the other competitor which is actually run by a subsidiary of the devil himself.
Always making my day when I see a new article about video card I jump right to the bottom and read the comments! :D

HULK SMASH!! LOUD NOISES!! FANBOY RAAAAAAAAAAAAAAGE!! ;)More seriously, an OC 460 is a little faster than a stock 6870. An OC 6850 is (very surprisingly) almost the same. At $180 for a 6850 vs $190 for a 460 1GB (current Newegg prices), the 6850 wins - although with such a tiny price and performance differential means it really boils down to color preference: do you like red or green? Competition FTW.
"Kicking to the curb" is over the top, but if it keeps the I❤AMD crowd from throwing another tantrum I'm cool with it.

Oh, 6850 compute performance fail. Now it matters say the amd fans - so hope they didn't do the stupid and get the 6850.Ryan Smith - Monday, November 8, 2010 - link
It was made abundantly clear to us in the comments in our follow-up piece and in emails to us that you guys disapproved of our inclusion of non-reference cards in articles. As we strive to reflect the needs and wants of you, our reader, we have taken your advice to heart. You will not be seeing the FTW or similar cards in any articles besides their associated roundups. As such articles like this will focus solely on the series being reviewed, and will not contain results from overclocked or otherwise non-reference cards that are not among the cards being reviewed.mac2j - Monday, November 8, 2010 - link
It was more about comparing: Reference vs Reference, OC vs OCThough I agree the best place for the 460 FTW is in a 6970 OC comparison article not a 6950 one.
As for this article "MSI R6850 OC is just all-around worse" makes no sense to me - as someone who doesn't care about noise and doesn't know a single person that really does in that kind of range ... of all these cards I would buy the MSI as it has by far the best price to performance.
I mean it's the only card that outperforms the 5850 and even, in a couple cases, the 6970 ... that's more performance for ~$50 less with similar noise... so calling it "all-around worse" is just crazy talk.... crazy talk man
Targon - Monday, November 8, 2010 - link
You mean 6870, right? The 6950 and 6970 have yet to be reviewed, at least in public, and we don't have any release date for the new high end parts, which will finally allow the 5870 to fade away as the top single-GPU cards from AMD.mac2j - Monday, November 8, 2010 - link
Ugh yea 68XX not 69XX ... been reading too many Cayman preview articles - sorry.
